Description
STANDARDISED BOTANICAL ACTIVE
5-HTP Powder 98%
5-HTP is supplied as a single-entity amino acid derivative at 98.0% by HPLC, released against a batch-specific certificate of analysis. It is obtained from Griffonia simplicifolia seed and is offered as a purified compound rather than as a seed extract, so the purchasing definition is the molecule and its declared purity. It is an industrial raw material for further processing and is not a finished consumer product.

Buyer Decision Guide
Agree the assay, the analytical method and the impurity profile before approval. Confirm whether the buyer’s specification calls for the purified compound or a Griffonia seed extract standardised to a lower 5-HTP content, since the two are released on different analytical bases.
- Assay: 98.0% by HPLC, released against the batch COA.
- Origin stated: Griffonia simplicifolia seed.
- Confirmed as the purified compound, not a standardised seed extract.
- Impurity profile reported per batch.
- COA, specification sheet and safety data sheet accompany each shipment.
- Regulatory status, permitted uses and labelling are the buyer’s responsibility for the destination market.
How This Grade Differs
5-HTP is offered as the purified compound at 98% and as a Griffonia seed extract standardised to a lower content. The extract also carries the other constituents of the seed, while the purified compound does not. They are separate products and should not be substituted without confirming the specification.
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
